I would like to see a more nuanced analysis of this. How many cases were there where the gun made a positive difference? The answers to the asked question don't really tell us much. I have had once a guy draw a gun on me while I was walking my dog and yelled at him because he almost ran me over. He would probably answer this question with "Yes" but this was certainly not defensive use and the gun made a normal dispute into a potentially life or death situation.
